The Preparation Of 2-Aminophenol-4-Sulfonic Acid From Sulfanilic Acid, Edward Jacob Mach

Theses

Sulfanilic acid (I) was examined for purity and character. Sodium and potassium salts were acetylated and their isolation and yields were investigated.

The salts were nitrated with mixed acids and the reaction mixtures were treated in various ways to ascertain a good method for isolating the desired 2-nitro-sulfanilic acid (II). An attempt was made to characterize the reaction products, and to devise quantitative methods to estimate the yield of 2-nitrosulfanilic acid. A previously unreported by-product of the nitration, 2,4,6-tri-nitroaniline (He), was isolated. Several new salts of 2-nitrosulfanilic acid were prepared, and a possible new derivative was observed from the reaction …

The Design And Construction Of An Electrolytic Cell For Aluminum Reduction, Thomas H. Melrose

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation was to design and construct a laboratory size electrolytic cell in which to reduce alumina, using the same basic materials that are used in a commercial size cell. The cell was designed to have a capacity of approxi­mately 100 grams of metallic aluminum produced every 8 hours. The cell was constructed so it could be operated continuously.

Investigation Of Inclusions In Armco Ingot Iron, Edwin J. Duncan

Bachelors Theses and Reports, 1928 - 1970

Various chemical and electrolytic separation methods were investigated in an attempt to separate the in­clusions in Armco ingot iron. Residues obtained were X-rayed for identification purposes. The microstruc­tures of this iron were studied with the object of de­termining the relative sizes, locations, and possible compositions of the inclusions.

Effect Of Recovery On The Recrystallized Grain-Size Of High Purity Aluminum, Rodney L. Helterline

Bachelors Theses and Reports, 1928 - 1970

When a cold-worked metal is annealed, it’s physical properties hange as a result of a new grain structure. The annealing treatment is divided into three stages according to the changes that occur in the distorted metal: (1) recovery, (2) recrystallization, and (3) grain growth.

Application Of Amalgam Metallurgy To The Extraction Of Indium, John Zelem

Bachelors Theses and Reports, 1928 - 1970

In view of the greater demand for indium with the progressive development of the metal, simpler methods of recovery are necessary. The author here hopes to apply mercury in the metallurgy of indium in an effort to find a simpler method of extraction.

Design And Calibration Of A Ferromagnetic Torsion Balance, Oliver W. Moen

Bachelors Theses and Reports, 1928 - 1970

Magnetic materials can be divided into three major groups; diamagnetic, paramagnetic and ferromagnetic. From a magnetic point of view, the ferromagnetic are the most interesting. Ferromagnetic materials include the elements iron, nickel, cobalt, certain of the alloys of these elements and a group of alloys first studied by Huesler. These latter are ferromagnetic largely because of the presence of manganese in special combination with the other non-ferrous elements.

Polarography Of Indium, John Jackson

Bachelors Theses and Reports, 1928 - 1970

Geology Of The Ragged Point Oil Field Musselshell County, Montana, David M. Amos

Bachelors Theses and Reports, 1928 - 1970

The Ragged Point oil field is located in Northwest Musselshell County, in the Lake Basin field of central Mon­tana, and on the western border of the Great Plains region. The surface topography is that of a plain marked by erosion and moderate folding. The stratigraphy of central Montana shows periodic marine invasions from the Cordilleran trough, with normal marine limestones interbedded with sandstone sand shales. These sediments are over 12,000 feet thick, with the Creta­ceous Eagle and Colorado formations exposed at the surface on the Ragged Point anticline. Undifferentiated Cambrian lime­stones and shales are the oldest rocks encountered in drilling.

Special Text, St 55-06-1, Transportation Intelligence, June 1954, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

This is a textbook used at the Army Transportation School. In the 1950s, military schools related to one of the Army Technical Services were run by that service. Since the format and content of Army field manuals were often very similar to those of special texts, the same staffs often prepared both. At the time this special text was written no field manual on transportation intelligence has been issued.

The modern US Army vision of the technical intelligence developed during World War II. Shortly before World War II, Army Technical Services had been instructed to set up intelligence sections in …

A Mathematical And Experimental Investigation Of The Application Of Air Spring To Shock Testing Machines, Eric E. Ungar

Mechanical Engineering ETDs

The applications of many modern devices require them to be able to perform their functions satisfactorily after having been subjected to transient accelerations of considerable magnitude. Some Devices are required to operate even during the period of acceleration.

Since failure of components or sub-assemblies during the actual operation of the entire assembly would in general be extremely undesirable and costly (for example, failure of instrumentation in a high-speed aircraft or guided missile might lead to loss of the entire vehicle), it is necessary to test the components and sub-assemblies in order to determine whether they may be exposed to accelerations …

Heat Transfer Characteristics Of Non-Newtonian Suspensions, Robert Gregory Quinn, Irving Bauman

Theses

This project was undertaken to collect additional information on the heat transfer coefficients of pseudo-plastic suspensions and to test the exponents of the equation of Salamone (12). Using the same equation as derived by Salamone by dimensional analysis, a better correlation of this data was obtained by changing some of the exponents to give the following equation:

LD/K_f=0.346(D_vp/M^{`</sup>)<sup>0.7</sup>(C<sub>f</sub>M<sup>`}/K_f)^0.72(D_s/D)^0.15(C_s/C_f)^0.35(k_s/k_f)^0.08 (1)

The authors believe that a better correlation is possible and …

Heat Transfer Characteristics Of Non-Newtonian Suspensions, Harold Binder, Paul Pollara

Theses

The following equation was developed by Dr. J. J. Salamone for calculating the fibs coefficient of heat transfer to non-Newtonian suspensions in turbulent flow (Re 50,000 - 200.000) inside of pipes:

h_D/K_f = 0.131 (DV_bPb/u_b)^0.62 (D/D_s)^0.05 (C_s/C_f)^0.35 (C_fu_b/K_f)^0.72 (K_s/K_f)^0.05

This equation was investigated to determine its validity over the lower turbulent regions of the Reynolds number (10,000 - 70,000), and to test the exponents of the various components.

Equipment was constructed similar …

Viscosity Determination During Polymerization, Elmer David Jones

Theses

This project was undertaken for the purpose of designing, constructing, and operating a viscometer which could be employed for measuring viscosities in the range of 200 to 700 poises at temperatures up to 300°C. Such an instrument was built and used to study the viscosity of Type EV polymer during polymerization.

The new viscometer is based cm the principle of concentric rotating cylinders. It is unique in that it can be suspended directly in a polymer batch and will operate under temperature and viscosity conditions as outlined above. Polymerization curves for batches studied show that the instrument gives viscosity values …

Investigation Of The Acid Degradation Of 2-(4-Methoxybenzylamino)-Pyridine, Anthony Thomas Oropollo

Theses

This paper represents work done in connection with an investigation of the products resulting from the reaction of dilute sulfuric acid and 2-(4-methoxybenzyl-amino)-pyridine. Brief contact between these reactants at temperatures below 80°C give rise to a water soluble salt of the amine. The amine may be precipitated from the solution by the addition of sufficient alkali.

Under the conditions considered in this paper, prolonged contact of reactants at temperatures above 80°C, a non-crystalline condensation product is obtained in addition to the amine salt.

Attempts to identify this product were unsuccessful. However, in connection with the characterization work, two relatively little …

A Study Of A Synthesis Of Indole, Stephen Scala

Theses

Chemical literature abounds with methods for the synthesis of Indole and its derivatives. Undoubtedly, this is so, because Indole is the parent substance of the historical dyestuff Indigo. This coloring material has been the subject of extensive investigations for many centuries. Early in this century, importance was still placed on Indole Chemistry, but it later gore way to other dyestuffs having different chemical structures. It seems, however, the loss in popularity was to have been short-lived, because of the revitalized interest shown in the chemistry of Indoles since the early 1930's.

It was found that a great number of alkaloids …

Geology Of An Area Near Montana City, Montana, Frank A. Crowley

Bachelors Theses and Reports, 1928 - 1970

The investigated area lies about five miles south of Helena, Montana, near the abandoned gold camp of Montana City. Topographically, the area reflects the sedimentary formations and the igneous rocks, quartz monzonite and rhyolite. Static recrystallization of the sedimentary rocks caused by the intrusion of the Boulder Batholith, along with deformation of sedimentary beds by pre-batholithic folding and by post-batholithic faulting have complicated the geologic picture.

The Placer Deposits Of The Siberia District (German Gulch), Montana, Ronald D. Karvinen

Bachelors Theses and Reports, 1928 - 1970

The original concept of this problem was to determine if hidden or buried placers existed past the terminal point of the extensive placering in the Siberia District. Several theories have been advanced for the sudden cessation of those placers. All are plausible, and are both for and against an extended placer. The past history relates that some $13,000,000 in gold has been produced in the area, therefore stressing a practical search for additional accumulation.

Leaching As A Method Of Mining Uranium, Rob L. Kane

Bachelors Theses and Reports, 1928 - 1970

This paper presents a new method of recovering uranium ores from the earth. By sinking drill holes into ore bearing beds, aqueous leach solutions can be circulated through the ores. Solutions of sulfuric acid, potassium carbonate and many other available reagents will put the ions of uranium and vanadium into the liquid leach. The pregnant solutions are then pumped to the surface so a recovery of the valuable portion of the ore can be made.

The Transient Response Of A Distributed Amplifier, Thomas D. Lusk

Electrical and Computer Engineering ETDs

The purpose of this paper is to describe the transient behavior of a simple constant-K distributed amplifier stage. The derivation of the transfer function is carried out using the Laplace Transform for the case where losses in the lines are considered to be zero. The various characteristics of the amplifier response to a unit step function are discussed and the effects of losses and other modifying factors upon the idealized response are evaluated. Finally design procedures are derived which allow the circuit designer to determine the circuit parameters necessary for good transient responses. These procedures are applied to the design …
